T0 aZZ whom it may concern:

Be it known that I, JEAN F. VEBB, Jr., residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Contact-Makers, of which the following. is a specification.

The invention is a contact maker espe cially designed for electric signaling and train control use, and it particularly has for its object to provide a contact maker by means of which good electrical connection between the train carried mechanism and the conductor rail may be had.

This application is a divisional part of my copending application, filed January 27, 191.0, Serial #540394.

The invention also resides in those novel details of construction, combination and arrangement of parts, all of which will be first fully described and then be specifically pointed out in the appended claims, reference being had to the accompanying drawing, in which Figure 1 is a side elevation of the contact maker. Fig. 2 is a vertical longitudinal section. on the line 22 ofFig. 1. Fig. 3 is a detail section on the line 3--3 of Fig. 2.

Referring now to the drawing, in which like numerals and letters of reference indicate like parts in all of the figures, the contact maker 17 comprises two angle irons 17 17 riveted together at 17 and secured by rivets 17 to the cross channel bar 1 of the wheeled truck, insulation 17 -17 being provided to electrically insulate the contact maker from the trucks. The angle irons 1717 each have a pair of vertically disposed slots 17 for the bearings 17 that carry the shafts 17 which are bolted at 17 to the hearings to hold the same from turning. Ball bearings 17 connect the shaft 17 e and contact wheels 17*. Pins 17 on angle irons 17 hold springs 17" to press down on the bearings 17 The angle irons 17 are riveted at 17 to the depending part of the angle irons 17, the rivets also passing through a spacing and bracing block 17. Contact fingers 1'7 on the blocks 17 engage the wheels 17* to insure good electrical con- Serial No 627,702.

tact, although such contact fingers may be omitted, if desired, as the wheels 17 are always in electrical connection with the block 17 and framing 17, through the axles 17 bearings 17 and springs 17, etc. The wheels 17 may have. lubricant holding chambers 17 into which a lubricant may be introduced through a bore 17 that is normally closed by a plug 17 The operation of the invention will be readily apparent by an inspection of the drawing, in which 21 designates the contact rail on which the contact maker runs to complete the electrical continuity between the rail 21 and the brushes and contact fingers 17 From the foregoing description taken in connection with the accompanying drawing, it is believed the complete construction, operation and advantages of the invention will be apparent tothose skilled in the art.

What I claim is l. A contact maker comprising a pair of angle irons secured together, and having depending parts spaced apart, said depending parts having bearing slots, bearing boxes, a shaft passing through said depending parts and secured from rotation in said bearing boxes, angle irons secured to said depending parts, spring holding lugs carried by said angleirons, springs on said lugs to engage said bearing boxes to tend to move said bearings in one direction, and a contact wheel rotatable on said shaft, all be ing arranged substantially as shown and described.

2. A contact maker comprising a pair of angle irons, secured together and having depending parts spaced apart, said depending parts having vertical slots, bearings mount ed in said vertical slots, a shaft mounted in said bearings, means continuously tending to hold said bearings in one position, a contact wheel rotatable on said shaft, and means insuring good electrical connection between said wheel and said angle irons.
